The spongy organ that processes about 11,000 litres of air per day/The Human Body
Each human lung contains roughly 300 million alveoli, providing a total surface area about the size of a tennis court. The right lung is slightly larger than the left to accommodate the heart. Together, the lungs process about 11,000 litres of air daily at rest.
